Odd GPU behavior - terminal window + FAHClient

[SJC_Steve]

-----------------------------------------------------------------------
Maybe it's just that FAH rewrites config and discards redundant statements. The default value for 'gpu' is 'true' so changing it to 'true' is logically the same as removing the 'false' modification from the default.

* I Purged the FAHClient and reloaded V7.6.21, filled out the User Name, etc. and then opened FAHControl. It shows only folding on cpu with Configure - Expert showing gpu = false.
* I also looked in config.xml and it shows gpu = false as well.
* Rebooting does not change these values and the machine will not fold on the GPU even though the OpenCL dev files and NVIDIA driver are present.

Are you certain that the gpu default = true? If so, how did the gpu=false occur in start-up process? It would seem that the default is set to false or the Client rewrites gpu=false during start-up. Either way, no gpu folding on my Linux machine.

If I change the value of gpu=true in FAHControl, Save and Reboot the Client simply removes the gpu attribute in Control and config.xml, it will not allow me to change it to true. But at this point it will start folding on the gpu with no gpu attribute.

So at this point, my Guide will include removing the gpu attribute in Control. I'd like to delete this step but at this point I'm at a loss as how to get the Client to come up without intervention for gpu folding on the current LTS version of Ubuntu.

I've included the logs from the start-up immediately following install of the Client.

Any thoughts?
Thanks, Steve

Note that the following is in your personal config

Code: Select all

20:20:12: <!-- Folding Slot Configuration -->
20:20:12: <gpu v='false'/>

This overrides the default and changes it from true to false.

Having this statement there will prevent the cliet's default behavior of reconfiguring your GPUs. Removing that option will allow the default value of true reconfigure your GPUs when FAHClient restarts.

[gunnarre]

You could try taking a backup copy of config.xml, removing the "<gpu v='false'/>" line from config.xml and re-starting with e.g.

Code: Select all

sudo systemctl restart FAHClient.service

There is a risk to breaking the config.xml file, but as long as you have a backup copy of it, it shouldn't be that bad to edit it by hand. Usually you never have to do this.

What do you mean by "my personal config"? At this point in the logs, I've done nothing but Purge the Client and reload it so it's a new start-up of the Client with no intervention by me. The new Client put the value of gpu=false in the config.xml file, not me.

That's why I've been asking whether you're certain that the Client default is gpu=true? Why did the Client put that value there when both the Nvidia drivers and OpenCL dev files were present and ready to go?

Thanks,
Steve

Good suggestions, thank you. But why do I have to go through this step at all? Why is gpu=false in the config.xml file to begin with? With a supported GPU, Nvidia files loaded and OpenCL files loaded and waiting, the Client starts-up with gpu=false?

I've done the reload of the PC several times and it very consistent, gpu=false always comes up and must be manually removed. Donors shouldn't need to do this step at all if we can figure out why it's happening.

bruce says that the default is gpu=true, so why in mine false? The start-up logs don't show me anything just that the config.xml file shows gpu=false, maybe they say something to you that can help eliminate this step altogether.

Thanks,
Steve

In the log above, there's this entry; 20:20:12: CWD: /var/lib/fahclient

When I looked in this directory, I found another directory named 'configs'

In the 'configs' directory are several .xml documents, so I opened the first one as follows;

/var/lib/fahclient/configs$ nano config-20210213-202113.xml

This is the text within the .xml;

<config>
<!--
This is a sample XML configuration file for the Folding@home
console client. This configuration file format is explained
in detail in the Client User's Guide.

Copy this file to 'config.xml' and edit.

To set your user name, team and passkey just edit the text
in quotes below.
-->

<!-- User Information -->
<user value="SJC_Steve"/> <!-- Enter your user name here -->
<team value="0"/> <!-- Your team number -->
<passkey value=""/> <!-- 32 hexadecimal characters if provided -->

<power value="full"/>
<gpu value="false"/> <!-- If true, attempt to autoconfigure GPUs -->
<fold-anon value="true"/>

As you can see, the notorious <gpu value="false"/> attribute is in this file which I have to assume is what was written to the working config.xml file upon start up of the Client. If the default value for gpu is true, how did mine come to be false?

Thanks, Steve

I don't have access to the code for the installer or FAHClient to verify all of this, but my understanding is the installer checks at initial installation time for an usable GPU, and sets the value to false if it does not find one. "Usable" in this case includes being whitelisted in GPUs.txt, driver and proper OpenCL implementation detected, and possibly some additional criteria. If set by the installer, this value is not reset by the automatic GPU detection code run by the client when it starts up.

So just fixing any issues with OpenCL or the driver is not be sufficient to change the value, it has to be done manually instead of by using a restart. I do know that the last time I checked the template config.xml file on my systems, it did not include the "gpu = false" entry.

There is one type of install that will always get the gpu=false setting. The option on Windows to do a Service install precludes the ability to use a GPU for folding. That comes from Windows security requiring the display belong to a logged in user, running as a service FAHClient does not count as being logged in.

I editted the value of gpu from false to true and also added this line under the CPU slot;
<slot id='1' type='GPU'/>

I ran the restart FAHClient command as you suggested but there was no change to GPU Folding, (not Folding) even though the config.xml said that gpu=true.

I had to reboot the PC for the Client to accept the new gpu value. After reboot, Folding started on the GPU.

However, the Client had deleted the gpu = true line in the config.xml file that I had manually added, it was gone.

So I'm still left with the dilemma of why I'm having to edit the config.xml file or change gpu parameters in FAHControl. I can get it to work, that's not an issue anymore but for the Guide I'm working on for newcomers to Folding, I'd like to eliminate that step but so far it requires manual intervention to get GPU Folding to work on my Linux machine.

Thanks,
Steve

One note, if you want to see all options, only the ones not set to their default values get saved to the config.xml file, you can do that. Set the logging verbosity to 5 instead of its default value of 3, the next restart of FAHClient will echo all settings to the log file. It is strongly recommended that the verbosity level be returned to the default (3) afterwards, the full dump of option values just gets in the way of troubleshooting.

What is the command to change the verbosity level, I looked in FAHControl but didn't see anything related to verbose level.

The place to do it was removed from the current FAHControl. You can add the Extra client option 'verbosity' and set the value to 5.

I added the option and as you said, came up with a much longer log. Here it is, what does it mean?

It successfully found the GPU and Cuda.
But the GPU=false is in the config.xml
Removing the flag ir changing it to True and a reboot should get you up and running.
This line here is where it gets the config file from.
Config: /etc/fahclient/config.xml
You'll need a sudo to edit files in /etc

Thanks for input, however, I don't want novices to be required to edit the config.xml file, it's too complex. I'd like input on how to avoid this step. Why is gpu=false ending up in my config.xml file and how can eliminate it happening?

Thanks, Steve

If the first time that FAHClient runs, it finds no GPUs with their respective drivers, FAH will add the gpu=false statement so that the next time you run it, it doesn't waste a few seconds reconfiguering GPUs:0.

I have not done a fresh install recently. If it does find a GPU and configure it, it may also decide that your GPUs are permanent parts of your kit and they're not going to change just because you restart FAHClient the next time you reboot.

Not editing the config is an excellent plan. Can you describe removing the entry using FAHControl? (and do you consider teaching FAHControl to be beyond the scope of what a newbie can absorb in their first sitting?)
